Yes. The overarching goal at the start of his campaign was to influence the Democratic Party, Hillary Clinton, and the country as a whole. Given Clinton's leftward shift to more Sanders-esque policies and rhetoric, he'll probably agree that he succeeded in his goal to some extent. He'll support Clinton wholeheartedly to carry his ideas into the White House.
No, the goal was to win, not to have Hillary feint left.
Do you really think Bernie thought he could win when he began his campaign?
Maybe later on it seemed possible to him, but initially there's no way.
